Answer:
£24 : £32
Step-by-step explanation:
Add the parts of the ratio 3 + 4 = 7
Divide the amount by 7 to find the value of one part
£56 ÷ 7 = £8 ← one part of the ratio
3 parts = 3 × £8 = £24
4 parts = 4 × £8 = £32
Answer:
Step-by-step explanation:
Using the alternative hypothesis (µ < µ0),
To find the p-value with test statistic -1.25 and assuming a standard level of significance of 0.05, using a p value calculator, the p-value is 0.1057 which is great that 0.05. Thus, the results is not significant.
Using the p value calculation.
1. Check the left tailed z table as the test statistic is negative,
2. Then find the probabilitythat z is greater than your test statistic (look up your test statistic on the z-table- the value under 1.2 and 0.05 which is 0.8944
3. Then, find its corresponding probability, and subtract it from 1 to get your p-value- 1-0.8944 = 0.1056.
Answer:
gradient = 2
Step-by-step explanation:
Calculate the gradient (slope) m using the slope formula
m = 
with (x₁, y₁ ) = (1, 0) and (x₂, y₂ ) = (6, 10) ← 2 points on the line
m = 
= 
= 2
Answer: D:
To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.
